Answer 1

In SharePoint v.2:

In SharePoint v.3:

• Max # list items : 2000 (per view, you can have million items as long as you don't display in a single view more than 2000 items)
• Max lists per site : 2000 is a "reasonable" number
• Effect when we reach the limit : Exponential degradation of performance when we enumerate more than 2000 items using the OM. An alternative is to use Search API or CAML queries.
